Description :
The 1999 Chi-Chi earthquake significantly altered the landscape of central Taiwan. Surface deformation produced by the earthquake along the trace of the Chelungpu thrust can be classified into 2 styles : uplift without significant surface rupture, and uplift accompanied by surface rupture. Here the AA. examine areas that exhibited the first style of deformation. It is proposed in this study that the differences in fluid properties affected by sediment constituents, frictional heating and possibly sulphate content of groundwater were probably the principal cause of diverse landscape deformation in response to the 1999 Chi-Chi earthquake.
